When you crap a massive log of shit the day after Christmas that percolated in your colon from Christmas dinner. These Yule log shits can take hours to pass due to the fact they are the size of a Chipoltle burrito. Often contains: ham, mashed potatoes, apple pie, gingerbread men, dinner rolls and other starchy/fatty drunk food.

My ass is covered in hemorrhoids from giving birth to the biggest yule log shit of my life. I was in labor for like 3 hours.
